min

Interface

template<typename T>
inline SPROUT_CONSTEXPR T const&
min(T const& a, T const& b);

template<typename T, typename Compare>
inline SPROUT_CONSTEXPR T const&
min(T const& a, T const& b, Compare comp);

Requires

Type T is LessThanComparable.

Returns

The smaller value.

Remarks

Returns the first argument when the arguments are equivalent.

Examples

#include <sprout/algorithm/min.hpp>
#include <sprout/array.hpp>
using namespace sprout;

SPROUT_STATIC_CONSTEXPR auto input = array<int, 10>{{-1, 1}};
SPROUT_STATIC_CONSTEXPR auto result = sprout::min(input[0], input[1]);
static_assert(result == -1, "min value is -1.");

Interface

template<typename T, typename Compare>
inline SPROUT_CONSTEXPR T
min(std::initializer_list<T> t, Compare comp);

template<typename T>
inline SPROUT_CONSTEXPR T
min(std::initializer_list<T> t);

Requires

T is LessThanComparable and CopyConstructible and t.size() > 0.

Returns

The smallest value in the initializer_list.

Remarks

Returns a copy of the leftmost argument when several arguments are equivalent to the smallest.

If an implementation not support C++14 initializer_list (SPROUT_NO_CXX14_INITIALIZER_LIST defined), then this function is not specified constexpr.

Complexity

Recursive function invocations in O(logN) (logarithmic) depth.
